PAPER-MAKING ivlACHlNE.

SPECIFICATION forming part of Letters Patent No. 304,091, dated August26. 1884*.

Application liled May 12, 1854. (No model.)

To (ZZZ whom, may concern/r Be it known that I, WILLIAM J. FOLEY, of

East Hartford, in the county of Hartford and State of Connecticut, haveinvented certain new and useful Improvements Pertaining to PaperhlahingMachines, of which the following is a description, reference being hadto the accompanying drawings, where.

Figure 1 is a view i1 side elevation of so much of the paper-niakingmachine as isnecessary to illustrate my improvements. Fig. 2 is a planview of the same, with parts in section to show construction. The frameand connected parts are cut away above the lines m a: of Fig. 1, theendless felt is removed, and

' also the upper part of the deckles.

My invention has for its object the making, by the use of machinery,sheets of paper that shall have all the merits and characteristics ofhand-made paper; and it consists in the method of making successivesheets of paper and in the means employed therefor, in the improvedbottom for the mold-box, in the device forimparting the desired surfaceto the paper between thcpress-rolls, and in certain details in theconstruction of the machine, as more particularly hereinafter described.

My invention is shown in the accompanying drawings as applied to theHarper improved 3o Fourdrinier machines, and the letter etherein denotesthe frame of the machine, of the material. and construction common tothe class stated; I), the wire; a, the ire-rolls, and d the smalltubular Wire-supporting rolls, arranged 3 5 in suitable hearings in theframe. The letter 6 denotes the coucher-roll, pivotally suspended.

in the coucher-frame f,- g, the endless felt, which passes over thecoucher-roll, over the felt-rolls 71, and between the press-rolls i j,

that are journaled in bearings in the ordinary manner.

The wire is adjusted as to tension by means of the adjustable rolls Z),supported in 1nova ble bearings having means for clamping them to thestandards 71", and the felt is adjusted as to tension by means of thetension-rolls g, which are moved in their bearings g by means of thethreaded shaft and connected mechanisni. These general features of themachine are of ordinary construction and operation.

The flanged pulleys Z are fast to the trans verse shafts m and supportthe deckles a, which, so far as the side dechles are concerned, are ofordinary material and construction; but at suitable intervals along thedeckles I arrange the transverse bars a, of like material as the bandswhich form the side decklcs, and these are preferably triangular incross-section, and arranged with the bearing faces of the crosspieees inthe same plane with the bearing-sun 6o face of the side dechles whenthey rest upon the wire. this means, as will be seen by a glance at Fig.2, a series of individual and separate compartments, of, are formed bythe contact ofthe side dechles and cross-bars with the wire.

The stuff, having been properly beaten and strained, is pumped from thestuff-box into the trough 0, from which it overflows into the firstcompartment at the left of the dechleframe. (Denoted in the drawings byFig. 1.) The crossbars of the (lechle, in connection with the sidedechles, hold a given supply of pulp in this forming-space or 1nold-b0X.

A movable bed, 1), preferably of india-rub- 7 5 her or the like elasticmaterial, is supported in the form of an endless apron by the rolls 0 pand by part of the rolls (1, and it extends below and slightly beyondthe forming-space in such manner that the bed is carried by the rollsunderneath the wire as it passes over the tubular rolls (1 in itspassage from end to end of the horizontal part of the wire. The waterdrains from the pulp as the wire and the deckles move along, until, asthe pulp passes 5 over the suction-box o, the greater part of themoisture is exhausted from the pulp in the ordinary manner.

By the devices already mentioned a continued series of successive sheetsare formed upon the wire between the sides and the cross-bars of thedeckles, and these sheets are transferred at. the coueher-roll from thewire to the felt 1 and they are moved with the felt along and over themachine in the direction indicated by the overlying arrows until theyare passed be tween the press-rolls 53'. If the upper pressrolls, 2',were of metal, the paper would stick to the rolls and would tear in theremoval;

but to prevent this and to give to the paper 00 I the desired appearanceon. both surfaces, I make use of the endless felt a-, supported bytransverse rolls 7- in bearings in the trainer. Ordinary ineansasthreaded shaft and wheel in combination with movable bearingsfare used,as shown at 1- r, for adjusting the ten sion of the felt '7- and thepressure between the press-rolls, respectively. The sheets, as they passbetween the felts at the press-rolls, continue to cling to either of thefelts with an equal tenacity, and the result is that gravity causes themto remain on the lower felt, g, from which they are removed at A by thenut chine-tender.

In the foregoing drawings many parts common to papcrnnaking machineshave been omitted, in order to make more clear the principal details ofmy invention; but enough of the connected parts have been shown to illnstrate my improvements.

The sheets of paper produced by this within-described process andmachinery have the peculiar surfaces and the peculiar decklecdge commonto hand-made papers.

I claim as my invent-ion 1. The within-described method of making sheetsof paper, which consists in forming the sheets in succession incompartments upon the wire of the paper-mahing machine of theFourdrinier type and subjecting the sheets to pressure between felts asthey pass between the pressrolls, all substantially as described.

2. I11 a paper-making machine, in combination with the wire,decide-ledges provided with transverse connecting-bars, whereby separateand distinct compartments are formed upon the wire, all substantially asdescribed.

3. In a paper-mal1ing machine, in combination, the wire, the dcckles,and an endless apron supported beneath the wire and traveling with thelatter for acertain distance along its horizontal. path, whereby amovable bed is formed, all substantially as described.

In combination, in a paper-making machine, the deckles having theconnected crossbars, the wire, and the endless apron arranged beneaththe wire, whereby a bed is provided for the formingsection, allsubstantially as described.

5. In a paper-making machine, the combination of the felt g and the feltr and their successive supporting and propelling rolls, allsubstantially as described, and for the purpose set forth.

(S. In a paper-making machine, the combi nation of the lower press-roll,j, upper pressrcll, t, and felts g and r with connected felt supportingand propelling mechanism, all substantiall y as described.
